2 2. Connectors and wiring You connect the computer and the displays with serial cables for the display control. You can use one of serial communication control ports with selecting whether RS-232C or LAN. A: RS-232C connection Connector: D-Sub 9-pin Cable: Cross (reversed) cable or null modem cable B: LAN connection Connector: Modular 8pin (RJ45) Cable: Modular 8pin (RJ45), Strait CAT5/6/7 LAN cable * If you connect one PC and one display without LAN HUB, you use Cross LAN cable. PC LAN HUB Display #1 Display #2 LAN cable LAN cables Note: LAN control is converted to RS-232C control in the display. (2/58)

3 3. Communication Parameter Set each communication parameters to the PC connected with each kind of cable. A: RS-232C connection (1) RS-232C direct connection between PC and Display Interface RS-232C (Asynchronous, Full-duplex) Baud rate 9600bps Data length 8bits Parity None Stop bit 1 bit Flow control None Communication code ASCII Communication signals TXD, RXD B: LAN connection (1) LAN connection between PC and Display Interface TCP/IP DHCP client mode Changeable (default = OFF: not using) IP address Changeable (default = : depends on model) Subnet mask Changeable (default = ) Default gateway Changeable (default = : depends on model) Port 3007/63007 (Both of those ports are available. Use only if you have no support of legacy products.) (3/58)

4 3.1 Communication timing The controller should wait for a packet interval before next command is sent. The packet interval needs to be longer than 600msec for the A3112(MDT701S/LDT701V). [Important Information] HOST system shall send next command after receiving a reply command from Monitor, if it is sequential commands communication. If Host doesn t wait for monitor s reply, monitor operation error may happen. Time-out error handling operation in Controller: Host Controller shall wait the reply from Monitor, after sending command as mentioned above. The time-out setting in Host Controller shall be more than 30sec after sending command to Monitor. (Using the maximum command interval a MAX is most safety.) Communication disabled period after power on/off: After Monitor Power on, either by AC switch, Remote Controller or Serial communication command, Monitor goes initialize mode of controller and can not handle the remote control commands correctly during the mode. So do NOT send any command at least 20sec after monitor power on/off. If you make the code which sends any command after POWER ON/OFF command, please put a wait at least 20sec after sending the command. About the other commands, please wait the each periods of command interval from PC. (See below example.) When your system may output no signal, you have to set the menu POWER SAVE (PC) to OFF because of 20sec waiting. [Available Command list at DC power off status] A3112(MDT701S/LDT701V) can t accept and reply any command except for the following commands when it is in DC power off or power saving. Power status Read / Read Model name Read / Serial number Read /Power on / Power off [Network latency with control via LAN] If you control A3112(MDT701S/LDT701V) via LAN interface, the network latency time will affect the control timing of serial commands. It is out of scope of document. Please add necessary margin of wait time and interval of each command packet, based on the maximum available latency time with your system and add appropriate error handling operation into your control program.

(This results in a MAX ) a > 15sec: When Command #1 is Force powered off. a > 600msec: When Command #1 is the others. * Minimum reply time from display (Additional time depends on command processing in display) b = 10msec (Typ.): On RS-232C connection (The time depends on models as 10 to 20msec.) b = 30sec (max): When Command #1 is FACTORY RESET, SCREEN RESET. b = 3sec (max): When Command #1 is video input command INPUT D-SUB, INPUT VIDEO,etc. b < 200msec (max): When Command #1 is the others. * Command internal gap (Don t make a longer interval gap between characters.) [Following 3steps of time out period is selectable by OSD menu CONTROL TIMEOUT in CONFIGURATION2 menu on POWER ON mode. Although c is 5sec on POWER OFF mode and sleep mode. ] c < 10msec: Normal communication mode for time-out error of each character gap. c < 2sec: Hand typing mode on teletype application. c < 30sec: Hand typing mode with longer time-out. (Infinity waiting isn t supported because of processing freeze.) (5/58)

6 4. Communication Format 4.1. Basic command This command set supports only the basic control of monitor and does NOT support multi monitor control by daisy chained connection. This command set will be written in the user s manual of A3112(MDT701S/LDT701V). 1) Control command diagram The command is structured by the address code, function code, data code and end code. The length of the command is different for each function. 2) Control sequence (1) The command from a computer to the LCD monitor will be sent in 600ms. (2) The LCD monitor will send a return command 600ms* after it has received and encoded. If the command isn t received correctly, the LCD monitor will not send the return command. (3) The personal computer checks the command and confirms if the command, which has been sent, has been executed or not. (4) This LCD monitor sends various codes other than return code. When having a control sequence by RS-232C, reject other codes from personal computers side. *: The sending time of return command may delay depending on the condition (during changing of the input signal, etc.). Example: Turn the power ON ( is for ASCII code) Note: The replied status is for communication confirmation. When you want to know the display condition, please use the Read command. (See page 7) (6/58)

7 3) Operation commands The operation commands execute the basic operation setting of this LCD monitor. It may not operate when changing the signal: Operation ASCII HEX POWER ON! 21h POWER OFF " 22h FORCE POWER OFF WITH OPS "" 22h 22h INPUT HDMI1 _r1 5Fh 72h 31h INPUT HDMI2 _r7 5Fh 72h 37h INPUT DVI-D _r2 5Fh 72h 32h INPUT D-SUB _r3 5Fh 72h 33h INPUT OPTION(OPS) _r5 5Fh 72h 35h INPUT DisplayPort _r6 5Fh 72h 36h INPUT VIDEO _v1 5Fh 76h 31h INPUT YPbPr (DVD/HD) _v2 5Fh 76h 32h INPUT S-VIDEO* _v3 5Fh 76h 33h * S-VIDEO is SEPARATE only 4) Read command Host computer sends the command without Data-code to monitor. After receiving this command, the monitor returns the command with Data-code of current status to host computer. < ex. > When Host computer ask Power status of monitor, the status of monitor is powered-on. Structure of the Read-command POWER Input Picture mode Temperature of Internal monitor ASCII HEX Function Data (Receive) Function Data (Receive) ON vp OFF(sleep/stand by) vp HDMI1 vi r HDMI2 vi r DVI-D vi r D-SUB vi r OPTION vi r DisplayPort vi r Video vi v YPbPr (DVD/HD) vi v S-VIDEO vi v HIGHBRIGHT vm p1 76 4D STANDARD vm p2 76 4D Around Main board Around Power PCB resolution 1 C tc1 (ex.)

8 5) Remote command (Not executable in sleep/standby mode. When the remote commands are sent while sleep/standby mode, the sleep/stand-by mode is only canceled.) Some remote control operations can be achieved by the remote command codes. The remote commands have no data codes. Button s name on remote Function Character ASCII +/VOLUME r06 72h 30h 36h -/VOLUME r07 72h 30h 37h AV MUTE ra6 72h 61h 36h AUTO SETUP r09 72h 30h 39h [Example] When executing the AUTO SETUP. (Figures and symbols enclosed in quotation marks are ASCII codes.): Sending commands from the PC, etc D 00r09 Status code from the projector Description Command operating the same as the MENU button D 00r09 Command receipt confirmation (Command echo back) Note: When you use a terminal application with typing the codes by hands, DO NOT type BS (Back Space) key or the other control keys. The behavior may send unexpected codes in Sending command to the monitor. The communication may be rejected by the monitor, or the monitor may result in unexpected operation in the worst case.

9 4.2. Extended command Note: This command set supports multi monitor control by daisy chained connection. This command set will NOT be written in the user s manual of A3112(MDT701S/LDT701V). The command packet consists of four parts,,, and. Check Code Sequence of a typical procedure to control a monitor is as follows, [A controller and a monitor, two-way communication composition figure] Controller Monitor Check Code Get Check Code Check Code Set Check Code The controller sends a command to get a value from the monitor that you want to change. The monitor replies with the current value of the requested item. The controller sends commands to set an adjusted value. The monitor replies to the controller for confirmation. Check Code Get Check Code Save Current Check Code The controller sends a command to get a value for confirmation. The monitor replies with an adjusted value. The controller requests to store the adjusted value to the monitor. (9/58)
